Indeed not. I don't intend to force 'my preferences' on anyone. I simply point out that if you don't control all the variables you can, you aren't sure of your own findings. I am as vulnerable to those confounders as anyone. I don't want to spend a great deal of money and then have no way of knowing whether I made an improvement or not. Better still, find out before buying rather than afterwards. If I cannot isolate the thing I bought from every other factor, I'm very likely to let the price I paid influence what I think about it. Don't believe me, believe Feynman âThe first principle is that you must not fool yourselfâand you are the easiest person to fool.â It is sad, but true, and also unsurprising.
So let's have no condescending sarcasm. I don't mind what other people believe, nor what they like to buy and believe sounds good. Their money, their business. The issue comes along when they say to others that they should buy it too. Then we need just even a little teeny bit of evidence. No?
